Samsung QN900D Neo QLED 8K vs Haier Q80FUX

The Samsung QN900D television demonstrates its high capabilities in light production in synthetic tests without any issues – 1400 nits is truly an impressive figure. It also showcased these capabilities in the first scene from the film "Life of Pi," where we see a brilliant burst of the rising sun. However, due to problems with the dimming algorithm, some issues can be noticed here. In the test scenes from "Sicario 2" and the second scene from "Life of Pi," these values are no longer as high and amount to around 500-600 nits. While this may not be the worst result among Mini LED televisions, one could expect more given the price of the television. Nonetheless, the television deserves praise for covering a wide colour gamut of DCP P3 at 96%. Although there are technologies offering higher values, this result is still satisfactory.

Alright, let’s move on to the topic that stirs up so much discussion, namely the capabilities of the television in HDR mode. Let’s state it clearly right away: the Haier Q80FUX is certainly not a brightness demon. The panel of this receiver can generate about 350 nits at peak, which in today’s terms is the absolute minimum to even talk about the presence of High Dynamic Range (HDR). On the positive side, this power is at least stable – regardless of which test pattern or film scene we used, the measurements consistently oscillated in the range of 300-350 nits. These are therefore results that are at best sufficient, definitely far from the dazzling display of capabilities we are accustomed to with more expensive models. Fortunately, there is one aspect in which the Q80FUX compensates for these shortcomings and does so impressively. After all, we are talking about a QLED television (more precisely PFS LED), which means that thanks to the quantum dot filter applied to the panel, it can generate really juicy, vibrant colours. These are not empty promises – a DCI-P3 colour gamut coverage of nearly 95% is an impressive result and directly translates into colours that are very pleasant to the eye and saturated.

The television QN900D offers a Filmmaker mode that has been created with the intention of watching films in the most natural way possible, however, this mode is not without certain flaws. For HD content, the white balance shows a dominance of red and blue colours, causing the image to take on pink hues. In contrast, for 4K HDR content, the situation is the opposite – the decrease in blue and red levels warms up scenes and shifts colours towards yellow tones. This is confirmed by Color Checker tests, which clearly show that colour samples are veering in this direction.

As for brightness and the associated contrast, the gamma is significantly impaired. The biggest issue is a noticeable jump at the beginning of the graph, which indicates that dark details are excessively brightened, resulting in a loss of depth in the darkest areas of the image – this is due to local dimming. For 4K HDR materials, the EOTF curve looks quite good, however, it remains below the reference level, impacting the overall dynamics of the image.

Factory settings for movie mode are rarely perfect, but in the case of the Q80FUX, we were confronted with a noticeable imbalance. In SDR content, the image was decidedly too warm, a result of excessive red in the white balance, giving the whole a slightly sepia tone. Ironically, in HDR materials, the television fell into the opposite extreme – an excess of blue caused an unnatural, cold effect in perception. However, it was not the capricious white balance that was the biggest problem with this television. The real culprit, responsible for the aforementioned issues, was hiding deeper. It turned out that the Q80FUX has completely miscalibrated gamma values and, crucial for HDR, a poorly executed EOTF curve. It was these erroneous factory settings that caused persistent clipping of the brightest parts of the image, overlaying them with that characteristic milky filter. Thus, we found the source of the problem. This state of affairs led to general, significant colour errors, which were easy to catch even for an untrained eye. Like every television we tested, we decided to calibrate this model as well, and the results of these adjustments can be found in the next paragraph.

After calibration, the Filmmaker mode can indeed be called worthy of its name. The white balance for both HD and 4K HDR content has been significantly improved, making colours more natural and consistent. The image has gained in realism, and pink hues in HD content have been effectively eliminated, as has the yellowish glow in 4K HDR content. Thanks to calibration, the television now offers much better colour reproduction, positively affecting the viewing experience.

As for brightness, the situation with gamma is now quite the opposite – at the beginning of the graph, there is a noticeable drop, making the darkest details harder to discern. The EOTF curve for 4K HDR content has remained largely unchanged and is still below the reference level, meaning the television still struggles to maintain proper brightness. This is related to the aggressive dimming algorithm that affects the overall brightness of the image. You can see how the television fights to maintain high brightness or perfect black.

Despite the limitations associated with local dimming, the Samsung QN900D has improved colour reproduction quality, as confirmed by the Color Checker test results – the colour samples are now much closer to the targets, making the image more natural and pleasing to the eye.

The results of our calibration procedures must, regrettably, be acknowledged as twofold. Generally speaking, the picture is undeniably better than before the corrections; however, the biggest winner of this process turned out to be SDR content. It is precisely there, after correcting the gamma and white balance graphs, that we achieved results that can confidently be called very good. After adjustment, the Q80FUX truly shines in standard dynamics, showing only slight errors in the most difficult skin tone reproductions. Unfortunately, the weakest link remains HDR content. Here lies the paradox: despite having calibrated the white balance to nearly perfection, the overall colour errors still remain at quite a high level. The reason is that the television continues to interpret static HDR10 metadata "in its own way," stubbornly enforcing that unfortunate image burn-out effect, which inevitably leads to significant distortions. Although we have successfully eliminated the factory excess of blue, it is precisely due to this interference of electronics that the screen still tends to stray into somewhat overly cold tones. That is just how this television is.

The fluidity of tonal transitions in lower-quality materials is impressive – the Noise Reduction feature effectively smooths tonal transitions while eliminating film grain. Although the removal of grain is not always desirable, the overall final effect looks very aesthetically pleasing, particularly for those who prefer a cleaner image.

When it comes to upscaling, or image scaling, QN900D shows the enormous potential of the new processor with AI technology. Images and materials in lower resolution are upscaled while preserving many details – for example, a photo of a model looks fantastic, free of unnecessary jagged edges, and the branches in the background are not overly jagged.

If there is one area where Haier clearly shows it still has a long way to go compared to the market leaders, it is digital image processing. The upscaling, well... is just alright. And that’s really about all that can be said about it. It does what is expected of it: it ensures that lower resolution signals do not scare us with harsh pixelation on the screen and do not look like a forcibly enlarged postage stamp. However, it is far from the finesse and “intelligent” sharpening that more experienced players in this market have developed over the years. The biggest shortcoming of the Q80FUX software is the almost complete lack of any additional "cleaning" and smoothing functions for the image. The receiver does not offer any noise reduction or gradient improvement mechanisms. This means that with older or heavily compressed materials, we simply have to come to terms with the fact that any imperfections in tonal transitions or blending of colours, which we mentioned earlier, will continually accompany us during the viewing.

Samsung QN900D is currently the fastest television in the world – literally. A refresh rate of 240 Hz in 4K resolution is an incredible value that PC gamers will surely appreciate. As for cinema fans, they will not be disappointed either – Samsung offers a 10-step clarity scale in the picture settings, allowing for image adjustments. We can choose whether the television should provide a smoother, theatrical effect at the highest settings, or a more cinematic experience, with visible frames, at the lowest settings.

The issue of motion fluidity and blurring is largely predetermined by the use of a 60-hertz panel, which naturally makes it difficult to recommend this receiver to enthusiasts of very dynamic content. Fortunately, in the Q80FUX, we find a few options (although, as we shall see shortly, in reality only one) that are supposed to improve the experience with older film productions. There is a "De-Judder" slider available, which actually controls the smoothness of the image and allows us to adjust it to our preferences: from raw, cinematic frame rates to a more theatrical, smoothed presentation. However, a true surprise awaits us just beside it in the menu. There is also a second slider, supposedly dedicated to removing blur – a feature we typically encounter in 120Hz panels to combat motion blur in sports. However, as we expected, recalling memories from the tests of the K85F model, this slider here is merely a façade. Its adjustment does absolutely nothing to the image and it simply appears to be an oversight by the product engineers who left a non-functional option in the software for this type of panel.

Samsung QN900D is a television that offers excellent compatibility with consoles and a range of features that gamers will appreciate. It has 4 HDMI 2.1 ports, although unfortunately without the full bandwidth of 48 Gb/s. Nevertheless, for the average user, this is more than sufficient. Additionally, the television supports Auto Low Latency Mode (ALLM) and Variable Refresh Rate (VRR), which means a smoother image and no screen tearing during dynamic gameplay. The G-Sync and FreeSync technologies also deserve attention, as they ensure optimal cooperation with consoles and computers equipped with the appropriate graphics cards, minimizing stuttering and providing a smooth image.

One of the unique features available only in Samsung televisions is the Xbox Game Pass app, which allows for game streaming without the need for a console. This is a very convenient solution that lets you enjoy your favourite games without the need to purchase additional hardware. Furthermore, the QN900D has a Game Bar – a special panel that enables quick access to game-related settings, making the configuration of game mode fast and intuitive.

Another interesting feature is a function called Auto Motion Plus Game, which is a special motion smoothing mode that can increase the frame rate (operating at a maximum for a 4K@60Hz signal). Importantly, this does not cause a significant increase in input lag, allowing the player to enjoy both greater image smoothness. All these features make the Samsung QN900D an excellent choice for those looking for a gaming television with the highest possible specifications.

Stepping into the realm of gaming, the Haier Q80FUX proves to be quite a decent companion for the "casual gamer". Onboard, we find highly desired features such as VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode). However, the biggest surprise is something else altogether. Although we are not dealing with a 4K@120Hz panel here, the television is capable of accepting and displaying a 120Hz signal at a lower resolution (Full HD). This is a very useful feature that allows for a conscious switch of the console to a lower resolution mode in exchange for significantly higher smoothness, which is a compromise entirely acceptable in the gaming world.

We won’t particularly complain about the lack of extras like the "Game Bar", as it's merely a nice addition. The most concerning issues arise when we delve into the world of HDR in gaming. Due to the television constantly adapting the signal "in its own way", setting the brightness on the console according to the HGIG standard is nearly impossible to achieve as per instructions. Worse still, in the Dolby Vision mode for gaming, the input lag increases to around 50 ms, which is a value high enough to render this mode practically unusable. However, in general, we would not recommend gaming on this television in HDR mode, so these are not such grave shortcomings. What is most pleasing is the presence of 120Hz in Full HD, which makes the Q80FUX a rather nice television for the occasional gamer.
